CASE STUDYCaloosa Yacht and Racquet Club Seawall Restoration

Located in picturesque Fort Myers, Florida, the Caloosa Yacht and Racquet Club is a vibrant community hub for homeowners and boating enthusiasts. Recently, the club encountered a pressing problem: significant voids and sinkholes developing behind its 1,200-foot-long concrete seawall, adjacent to several residents’ backyards.

Heavy rainfall and scour activity had eroded the soil beneath and behind the seawall, causing alarming structural stress. These issues threatened not only the seawall’s integrity but also the safety and enjoyment of waterfront leisure walks.

Comprehensive Assessment and Damage Evaluation

Before repairs began, Seawall Savers conducted an in-depth assessment to determine the extent of damage and develop a tailored solution. Key evaluation factors included:

▲ Soil Composition: Detailed analysis of local soil types (clay, silt, sand) influencing erosion behavior.
▲ Seawall Cracks: Identification of crack locations, sizes, and types (surface vs. structural).
▲ Erosion & Sinkholes: Measurement of soil loss and voids behind the seawall.
▲ Corrosion Check: Inspection of metal reinforcements for rust and deterioration.
▲ Project Scope & Budget: Collaboration with the club board to align solutions with budgetary constraints and expectations.

Innovative Seawall Repair Techniques Employed

To maximize efficiency and minimize disruption, Seawall Savers™ implemented a multi-pronged repair strategy using cutting-edge technology:

Jet Filter Installation for Water Flow Management

A total of 150 maintainable “Jet Filters” were precisely installed in weep holes to control hydrostatic pressure and prevent future erosion behind the seawall.

Seawall Braces for Structural Reinforcement

Seventy-five durable Seawall Brace Panels were driven 7-8 feet deep into the substrate beneath the mudline, stabilizing the seawall slabs and halting upland soil erosion. For highly deteriorated sections, thirteen concrete-filled vinyl panels were installed for extra support.

Epoxy Injection for Crack Repair

Seawall cracks were meticulously sealed using a two-part epoxy grout injected under pressure. This method restored structural integrity by filling fissures and preventing water intrusion.

Soil Compaction to Fill Voids

Voids and sinkholes behind the seawall were filled with compacted soil to increase soil strength and reduce permeability, helping to prevent future erosion.

Project Overview and Results

Using specialized equipment such as the Vermeer CX 160 hydraulic submersible drill, the team completed the entire project within approximately two weeks.

▲ 150 Jet Filters installed to maintain proper drainage
▲ 75 Seawall Brace Panels driven into substrate
▲ 13 concrete-filled vinyl panels placed for severely damaged areas
▲ 185 feet of seawall cracks repaired with epoxy injection
▲ Use of 316 stainless steel fasteners ensured corrosion resistance

The result: a reinforced, resilient seawall that safeguards the coastal property efficiently, without costly full replacement or prolonged downtime.
